fw_cfg: add write callback
Reintroduce the write callback that was removed when write support was removed in commit 023e3148567ac898c7258138f8e86c3c2bb40d07. Contrary to the previous callback implementation, the write_cb callback is called whenever a write happened, so handlers must be ready to handle partial write as necessary.
